The ISI Annual Conference is the preeminent event for AEC industry professionals committed to fostering sustainable, equitable, and resilient civil infrastructure. Last year, we welcomed a record-breaking 1,800 participants from 52 different countries to this two-day virtual event to engage and explore new ideas about how infrastructure can better serve our communities. Attendees included engineers, planners, designers, consultants, architects, developers, construction and procurement professionals, owners, operators, government leaders, students, faculty, and more. Whether you’re a sustainability and resilience infrastructure expert or a curious novice, we hope you’ll join us to learn more about the latest trends and insights in sustainable infrastructure. Plus, by attending, Envision Sustainability Professionals (ENV SPs) can earn all of their annual credential maintenance hours!
